The Estonian composer and Orthodox convert Arvo Pärt wrote some years back a setting of 24 prayers by St. John Chrysostom for every hour of the day and night. Here is the English translation used in the piece.

Does anyone know where I can find the original Greek of these prayers? What is the standard edition, if any, of Chrystostom's works that one should go to in cases like this?

It is one of the standard prayers said before sleeping. It features in most Orthodox prayer books. I would have thought a basic Greek prayer book would include it.
